My cable box (from MediaOne/ATT/Comcast) is a DCT-???? with firmware
7.74. I tried the changechannel.py script from mythtv/contrib in CVS,
and it almost works straight out of the box:
I connected a pass-through 9-pin cable from serial port 1 (not 0 so I
didn't have to modify the script) to the Motorola/GI box.
I ran the script to change to channel 42, and I saw the digits '0', '4',
and '2' appear on the DCT's LCD one at a time, and then it changed back
to the previous channel. I had the same results trying to change to
channel 042.
So the box is at least receiving some signal, so the port is
active--that's good.
The only thing I see is that it's rather slow in sending the digits. So
I watched the on-screen display, and saw that it was dropping the first
digits before the last arrived. If I hit the last digit right after it
sent the '4' then it changed channels.
Any thoughts on how to speed it up?
